Fig. 1 – Free Standing Fires M20 and M12-F.

Components

* The combustion chamber and casing of all our Free Standing Fires are made of top-quality carbon steel plate with a thickness of 0.1 inches (5mm) and 0.019 inches (1.5mm), respectively.3 The M12-F model includes a stainless steel oven with a gas exhaust duct connected to the flue;

* The front panel and ash grate are made of grey cast iron.

* Heat-resistant ceramic glass. Can withstand temperatures of up to 1382°F (750°C) in continuous use;

* Heat-resistant paint for temperature peaks up 1652°F (900°C) and operating temperatures in the order 1112°F (600°C);

Installation

Attention: all regulations and standards must be complied with when installing this unit.

1. Combustion air and gas circulation

* This type of stove should be installed in well-ventilated areas. Any air

intake grilles should be placed in locations that are not liable to become blocked;

The combustion chamber in models M20 and M30 has a thickness of 3mm.

* The combustion air enters the fire through the combustion air intake damper on the front of the unit. This flow should be kept clear at all times;

* Additional air inlets may be needed if the stove is used in simultaneous with other devices that require an air supply. The installer should evaluate the situation according to the overall air flow requirements;

* Under normal operating conditions, the combustion gas flow should create a draught of 12 Pa one metre above the throat of the flue. For proper installation, at least 78.7 inches (2 metres) of metal flue tube with the same diameter as the unit's smoke outlet should be fitted vertically above the unit. After this section, sections of tubing with a maximum angle of 45° may be used; Figs. 2 and 3 illustrate correct and incorrect angles for installing a bend, if required.

45º45º45º

45º45º

Fig. 2 – Correct angle for bends Fig.3 – Incorrect angle for bends

* A single-walled tube installed on the outside of a building results in the condensation of water vapour in the combustion gases. Instead, use of a double-walled, insulated tube is recommended;

* The flue outlet should allow for good air circulation and be placed at least

23.6 inches (60cm) above the top of any obstacle located within a distance of 9.8 feet (3m);

* The ash grate should be installed with the narrow slots facing upwards;

* The same flue should not be used for more than one unit or open fireplace. With shared chimneys, each flue should reach its outlet independently and these should be at the same level to ensure that the air circulation expels the gases;

* Brick chimneys should not be too wide, as the smoke will cool as it disperses, reducing the draft. In case of draft problems, a revolving chimney cowl can be installed;

2. Installation location requirements

* The unit should stand on a masonry hearth made of refractory bricks or another type of non-combustible material; * Combustible materials should not be installed close to the walls of the stove;

* The floor on which the unit will stand must be able to support a permanent load of 2.2 pounds (1kg)/cm ². If the load capacity of the floor is insufficient, a solid plate can be used to distribute the load over an area

larger than the unit’s base;

* The building’s air intake grilles should not be obstructed;

* Ensure that the structure built into the wall is of an appropriate size to house the unit;

* Materials/objects placed near the stove should be able to withstand the heat radiated from the glass and walls, so should not be combustible;

* Refractory cement or other refractory material should be applied on the chimney walls.

* The use of wood finishings may increase the risk of fire. Therefore, we recommend the use of adequate insulation or that wood not be used at all.

3. Forced Ventilation and Circuit Diagram

* Units that are equipped with forced ventilation include two 9 W ventilators that generate an air flow of 8 cubic mile (84m3) /h each, connected in parallel through a thermostat according to the circuit diagram below.

Fig. 4 – Circuit diagram

Attention: all three wires in the power feed cable – earth, neutral and live – should be

connected. We take no responsibility for any damage resulting from non-compliance with this warning.

* The electrical components should always be connected to the power supply;

* The cable used for the electrical connection should be silicon-coated and heat-resistant to 356°F (180°C). If the power feed cable is damaged, it should only be replaced by a qualified technician;

* You should take care to not lay the cable where it may be crushed;

* The electrical installation should incorporate means to switch the unit off, with a minimum separation of 0.118 inches (3mm) between the contacts, pursuant to the applicable legislation in force.4

Instructions for Use

Attention: all regulations and standards must be complied with when installing this stove.

1. Fuel

* Only firewood should be used in this type of unit. It may not be used as an incinerator, nor should other materials such as coal, painted wood, varnishes, thinners, liquid fuels, glues or plastics be used. Also avoid burning common combustible materials such as cardboard and straw;

* Exotic firewood should also not be used as fuel;

* The firewood should have low water content (less than 20%). We advise that it should be placed in covered storage for around 2 years after felling, in order to ensure efficient combustion and avoid creosote build-up in the smoke duct, combustion chamber and on the glass; see Table 2, which lists some of the types of wood that can be used in these units;

We recommend the use of a 30 mA differential switch and a 0.5 A circuit breaker for the unit’s

electrical installation.

1.1. Power

The power of your unit indicates its heating capacity, i.e. the energy your unit transfers from the firewood to your home (usually measured in kW) and is directly related to the amount of firewood that you place in it.

The rated output is the measure of a standard load of firewood when tested in laboratories during a certain amount of time.

The power output is a manufacturer's recommendation from tests to the equipment with firewood loads within a reasonable operation range. This power output range will present different firewood consumptions per hour.

1.2. Energy Efficiency and Performance Ratings

Implementing solutions that seek to achieve greater energy efficiency allows for substantial reductions in energy needs, and thus reduces our current dependence on fossil fuels and other non-renewable sources of energy.

Energy efficiency enables you to make large savings from both an economic and an environmental point of view.

As a result of Solzaima's commitment towards the equipment's efficiency, most of our products are classified as efficiency class 1, i.e., with an efficiency rate equal to or greater than 70%.

A 70% efficiency rate means that 70% of the energy contained in the firewood is used to warm your home or, in other words, you are able to produce the same amount of energy with much less firewood.

*in accordance with EC classification standards for insert fires.

A Solzaima 5kW unit with an efficiency rate of 75%, i.e. efficiency class 1, will consume approximately 3.5 pounds (1.6kg) of firewood per hour to warm a 389 sq ft room (35m2).

Typically, a traditional fireplace has an efficiency rate of approximately 10%, which means it will consume about 26.5 pounds (12kg) of firewood to produce the same 5kw necessary to warm the same 389 sq ft room (35m2).

A traditional fireplace with an efficiency rate of 10% consumes 26.5 pounds (12kg) of firewood

A fireplace equipped with a simple fire (class 4) and providing an efficiency rate of 30% consumes 8.8 pounds (4kg) of firewood

A fire with an efficiency rate of 50% (class 3) consumes 5.3 pounds (2.4kg) of firewood

A Solzaima fire with an efficiency rate of 75% (class 1) consumes only 3.5 pounds (1.6kg) of firewood

2. First Use

* Ask the installer to light the unit to ensure that all is functioning correctly;

* The stove’s paint is cured by the heat when it is first used, which may give rise to additional smoke. If this happens, you should ventilate the room by opening external windows and doors.

3. Normal Use

* Lighting: a) Open the flue damper completely – lever on the top right-hand side of the unit (where applicable);

b) Place some pine cones (preferably) on the ash grate;

c) Place some kindling wood on top, piled horizontally; d) Open the combustion air intake regulator;

e) The lighting period is over when the body of the unit has reached a constant temperature. You should then regulate the combustion air intake;

* You should check that there is sufficient ventilation in the room where the unit is installed, otherwise it will not work properly. For this reason, you should check if there are any other heating devices which consume air during operation (e.g. gas-fired equipment, braziers, etc). We recommend against using these devices all at once;

* The air for combustion is drawn from the surrounding room, consuming oxygen. You should check that ventilation grilles and other devices for allowing air to enter from outside remain unobstructed;

* You must open the flue damper (where applicable) before reloading the stove with firewood. First, open the flue damper completely, then wait a little while to allow a good draught, and only then open the door slowly to prevent drawing smoke out into the room;

* You should only open the door during reloading. Normal conditions of use require the door to remain closed;

* Reload before the previous load has burnt completely, in order to make it easier for the combustion to continue;

* Use of the unit is not recommended when weather conditions are so bad that the draught is seriously affected (particularly when there are very strong winds).

4. Safety

* The ventilators should always be connected to the power supply (where applicable);

* You should take care to not lay the cable where it may be crushed;

* The exposed metal parts reach high temperatures - 212°F (100°C) on the door and 140°F (60°C) on the frame. The door handle does not reach temperatures above 113°F (45°C). Do not touch the hotter areas;

* You should use a glove or other protection if you have to touch the unit when it is in operation;

* In case of fire in the flue, immediately close the door, flue damper (where applicable) and air intake;

* If there is a power cut, resulting in the ventilators cutting out when the unit is in operation, close the combustion air intake and do not load the unit with any more firewood. Keep the door closed;

* We recommend you only use spare parts supplied by the manufacturer – SOLZAIMA.

5. Cleaning and Maintenance

* You should remove ash from the drawer on a regular basis (after the unit is switched off), so that the combustion air can enter through the ash grate unobstructed;

* The window should be cleaned with a suitable product,5 by following the instructions for use and not allowing the product to come into contact with the sealing string and painted metal parts, which could initiate oxidation. The sealing string is glued; therefore it should not be moistened with water or cleaning products. If it becomes detached, it can be reattached with contact glue after cleaning the groove with fine sandpaper;

* You should not clean the cast or plate iron parts with detergents. These should be cleaned with just a dry cloth to remove the dust and you may treat the cast iron parts with a special polish6 as often as you feel necessary.

* We advise you to clean the flue and flue throat (at the exit of the unit) at least once a year. This can be done by removing the baffle plate (removable plate in the ceiling of the combustion chamber);

* If you do not use the unit for a prolonged period, check to make sure that the flue pipes are clear before lighting it;

Seek advice from your installer.

from energy present in the firewood – measured for a standard load of firewood over a given period of time.

* Power output: a manufacturer's recommendation from tests on the equipment with firewood loads within a reasonable operating range. This power output range will present different firewood consumptions per hour.

* Plumb: vertically above the installation. * Efficiency: expressed as a percentage of “useful energy” that can be extracted

from a given system, taking into account the “total energy” of the fuel used. * Ignition temperature: temperature above which the fuel can enter into

combustion. * Heat-resistant: resistant to high temperatures and thermal shock. * Ceramic glass: Highly resistant ceramic material produced through controlled

crystallisation of vitreous materials. Used widely in industrial applications. * W (Watt): SI unit of power.
